Abstract
Eight larvae of the new subspecies Coryphista meadi atlantica Munroe, the barberry geometrid, were reared from eggs. Hatched eggs, first-instar larvae, head capsules of the various instars, one last-instar skin, and seven last-instar larvae were preserved for the present study. The head capsules indicated only four instars. The female adults were identified by Dr. E. G. Munroe, Systematic Entomology Unit, Entomology Division.
